Abstract

The present invention provides a process for preparing high nutritive fibres from fish proteins which comprises grinding whole fish or fish pieces in the presence of water and then adding alkali to the ground fish. The alkali/fish mixture is then heated and cooled and the cooled mixture is then passed through a colloid mill thereby eliminating solid particles to obtain a protein solution. The solution is then injected through a spinneret into an aqueous acid medium causing the coagulation of the proteins into fibres. The fibres are then washed, set by heating and then neutralized. The fibres obtained by this process are also described.

  1. 1. A process for preparing fibres from fish proteins which comprises successively:(a) grounding whole fish or fish pieces in the presence of water, the water to fish ratio being 0.7:1 to 2.5:1 by weight,(b) adding alkali to the ground fish in an alkali to fish ratio of 0.5:1 to 1.5:1 by weight based on dry matter,(c) heating the alkali/fish mixture of step (b) to a temperature of 60.degree. to 100.degree. C. for 0.5 to 3 minutes,(d) cooling the mixture of step (c) to a temperature of 35.degree. to 60.degree. C.,(e) passing the cooled mixture of step (d) through a colloid mill, eliminating solid particles and optionally concentrating to obtain a protein solution having a dry matter content of 6 to 10% by weight,(f) injecting the alkaline solution of step (e) through a spinneret into an aqueous acid medium having a pH of 0.7 to 0.9 and an ionic strength of 2.0 to 2.2 thereby to coagulate the proteins to fibres,(g) washing the fibres of step (f),(h) setting the fibres of step (g) by heating, and(i) neutralising the fibres.
